摘要
简单介绍了电网谐波的有关知识及危害,并对伊河电网220 kV中心变电站、人民水电站的谐波测量数据进行了分析。这是一次跳闸事故引发的对伊河电网谐波污染源的追踪和治理,从而保证向电网广大用户提供符合国标的、更为安全洁净的能源。
The thesis introduces some knowledge on harmonic in power grid and its harmfulness, analyzes the Harmonic data from the 220 kV Center Substation and Renmin Hydropower Station of Yihe power grid. The harmonic in the grid initiated a trip accident. The harmonic contaminant source is traced and e-liminated to ensure the electric energy conforming to the standard of the state and supplying safer and purer electric energy to the users of the power grid.
